>The bigger trouble with scripting is that the environment the script runs in may be somewhat isolated - may it wouldn't inherit the current dataenvironment, or wouldn't know of private variables of the caller etc (read as: I haven't tried this).

It's the same as calling PRG, the local variables are invisible, privite are visible and so on.

That's what ExecScript does.
